Epic Axis and Allies Board, need help

Good day,
Recently I undertook the challenge of creating a large Axis and Allies board on two pieces of pine. I have some experience with staining but given the scope of the project I want to get some pro tips. Here's the deal with the board, picture is attached below:
The two pieces of pine are attached via hinges, making the total size of the board about 2x3 ft. I used a wood burning tool to do all the lines. I purchased minwax water based stain for the colours and am very happy with the results. The minwax pre-stain is great as it also prevents sharpie from bleeding. I have already done a lot of sharpie work for the writing and it looks great. For my initial poly coat I have a can of waterbased spray and will be doing many light coats to prevent the sharpie from bleeding.
Now here's the rub. I really want to add oil based poly for my final coats. I am worried that with all the water based stain, sharpie and water based poly that if someone spills a beer on the board it will reactivate everything and possibly wreck it. I have a can of paint on water based poly as well. I like the colors as they are now so I also don't want to apply anything that will drastically change the color.
Some thoughts, insights and ideas on this matter would be helpful.

 

Welcome to the forums! Marksr will be by shortly. He is our paint guru. I don't understand why you want to overcoat it with oil base poly. The waterborne poly is pretty tough.

 

I suggest you do a test board, ideally with all the layers you have already applied. That's the best way to be sure you won't have any trouble with adhesion or other problems.

 

A spray acrylic sealer would probably work, test first. That would be a matte finish though and maybe undesired.

You could check out materials used for decoupage projects. Mod podge is used to protect and seal delicate items under it.

 

Oil based poly will yellow over time.

 

Thanks for your replies. Thats just it about the water based poly, will it stand up to liquids as welll? I'm not terribly concerned but I've put in enough work that i would like it to last for ages. I'll be doing many layers as well. Im probably just being overcautious. I do have a test board with all the same stuff on it so I will definitely do that too.

 

My tester board showed that everything looks great. The water based poly is awesome. Thanks for your information and insight. Next time I'll post my project properly.

A little late but water based poly would have been my suggestion since oil based has some amber color to it and I think you would want to avoid adding anything like that to your project.

 

BTW, that's a really nice looking board!
